A new model is developed to show how brain produces consciousness

According to the report of Swiss Federal Institute of Technology in Lausanne (EPFL) website, the school in collaboration with other university researchers proposed a two-stage model to explain how the brain processes unconscious information and turns the unconscious information into the conscious. According to this model, consciousness does not continuously arise but every once in a while. There is up to 400 milliseconds between the unconscious state and consciousness. There is no sense of time in this compartment.

The researchers published the paper in Public Library of Science • Bio recently, pointing out that people feel the world around is seamless and smooth, but it is an illusion. Some recent experiments show that the information is not the outside world into the conscious awareness continuously, but the brain collects such information in discrete time points, after treatment rendered. Like every second of film 24, as too fast and let us put mistaken continuous.

The researchers studied data previously published experimental psychology and behavior, with a two-stage model describes the information processing consciousness. First stage of the unconscious: the brain processes certain characteristics of things, such as color, shape, duration, etc., in the unconscious state with high time-frequency analysis of them, during this period no sense of time, but also feel not change the characteristics of things, time, wherein the digital signature is encoded, as color coding, as shape. Then the stage of consciousness: unconscious after processing is complete, the brain and gives all the characteristics of the final "picture", i.e. the brain and finally presented the things that make us aware of this information.

The whole process from the outside to stimulate awareness of cognition, the duration of up to 400 milliseconds. From a physiological point of view, this delay is quite long. First author, EPFL psychophysics lab Michael Herzog explained, "Because the brain want to give you the best, most clear message, which spend a lot of time for you to realize that it's no good unconscious processes because it will make people very confused."

The researchers noted that this was the first two-stage model of how consciousness arising, providing a more complex explanation for how the brain manages consciousness. It also provided new insights on for the relation between brain processes information and how we recognize the world.
